It is commonly believed that tornadoes happen mostly in the spring, but the peak of tornado season varies with location, and tornadoes can occur any month of the year. For example, the peak of tornado season in the northern plains and upper Midwest is June or July but it is from May to early June in the southern plains, and even earlier in the spring for the Gulf Coast.
Another common myth is that you should open your windows to allow the pressure to equalize should a tornado strike your home. Do not waste your time opening windows. If a tornado strikes, it will blow out the windows, and the last place you should be is near a window, where there is the greatest danger from flying debris and glass.
